| 1 | Management of hepatocellular carcinoma with portal vein tumor thrombosis: Review and update at 2016显示文摘Portal vein tumor thrombosis(PVTT) is a common phenomenon in hepatocellular carcinoma(HCC). Compared to HCC without PVTT, HCC with PVTT is characterized by an aggressive disease course, worse hepatic function, a higher chance of complications related to portal hypertension and poorer tolerance to treatment. Conventionally, HCC with PVTT is grouped together with metastatic HCC during the planning of its management, and most patients are offered palliative treatment with sorafenib or other systemic agents. As a result, most data on the management of HCC with PVTT comes from subgroup analyses or retrospective series. In the past few years, there have been several updates on management of HCC with PVTT. First, it is evident that HCC with PVTT consists of heterogeneous subgroups with different prognoses. Different classifications have been proposed to stage the degree of portal vein invasion/thrombosis, suggesting that different treatment modalities may be individualized to patients with different risks. Second, more studies indicate that more aggressive treatment, including surgical resection or locoregional treatment, may benefit select HCC patients with PVTT. In this review, we aim to discussthe recent conceptual changes and summarize the data on the management of HCC with PVTT. | Stephen L Chan Charing CN Chong Anthony WH Chan Darren MC Poon Kenneth SH Chok | 2016 | World Journal of Gastroenterology2016，22，32： | 44 |
| 2 | Role of LPS/CD14/TLR4-mediated inflammation in necrotizing enterocolitis:Pathogenesis and therapeutic implications显示文摘AIM:To establish the roles of lipopolysaccharide (LPS)/CD14/toll-like receptor 4 (TLR4)-mediated inflammation in a rat model of human necrotizing enterocolitis (NEC).METHODS: Six pairs of intestinal samples from human NEC were collected before and after recovery for histological and molecular analysis of inflammatory cytokines and signaling components. In the rat NEC model, we isolated 10-cm jejunum segments and divided them into six groups (n=6) for sham operation, treatment with LPS, bowel distension, combined bowel distension and LPS stimulation, and two therapeutic groups. The potential eff icacy of a recombinant CD18 peptide and a monoclonal CD14 antibody was evaluated in the latter two groups. The serum and tissue levels of several inflammatory mediators were quantified by real-time polymerase chain reaction, ELISA and immunoblotting.RESULTS: Human acute phase NEC tissues displayed significant increases (P<0.05) in levels of TLR4, CD14, myeloid differentiation protein (MD)-2, tumor necrosis factor (TNF)-α and nuclear factor-κB when compared to those after recovery. The histological and inflammatory picture of human NEC was reproduced in rats that were treated with combined bowel distension and LPS, but not in the sham-operated and other control rats. Serum levels of interleukin-6 and TNF-α were also elevated. The NEC pathology was attenuated by treating the NEC rats with a monoclonal CD14 antibody or an LPS-neutralizing peptide.CONCLUSION:LPS and distension are required to produce the histological and inflammatory features of NEC. A potential treatment option is blocking LPS activation and leukocyte infi ltration. | Kwong L Chan Kwong F Wong John M Luk | 2009 | World Journal of Gastroenterology2009，15，38： | 17 |
| 3 | Clinical significance of loss of heterozygosity for M6P/IGF2R in patients with primary hepatocellular carcinoma显示文摘AIM:To investigate the relationship between loss of heterozygosity (LOH) for mannose 6-phosphate/insulin- like growth factor 2 receptor (M6P/IGF2R) and the outcomes for primary HCC patients treated with partial hepatectomy. METHODS: The LOH for M6P/IGF2R in primary HCC patients was assessed using six different gene-specific nucleotide polymorphisms. The patients studied were enrolled to undergo partial hepatectomy. RESULTS: M6P/IGF2R was found to be polymorphic in 73.3% (22/30) of the patients, and of these patients, 50.0% (11/22) had tumors showing LOH in M6P/IGF2R. Loss of heterozygosity in M6P/IGF2R was associated with significant reductions in the two year overall survival rate (24.9% vs 65.5%; P = 0.04) and the disease-free survival rate (17.8% vs 59.3%; P = 0.03). CONCLUSION: These results show M6P/IGF2R LOH predicts poor clinical outcomes in surgically resected primary HCC patients. | Hong Seok Jang Ki Mun Kang Byung Ock Choi Gyu Young Chai Soon Chan Hong Woo Song Ha Randy L Jirtle | 2008 | World Journal of Gastroenterology2008，14，9： | 12 |

| 7 | Diagnosing gastrointestinal illnesses using fecal headspacevolatile organic compounds显示文摘Volatile organic compounds(VOCs) emitted from stool are the components of the smell of stool representing the end products of microbial activity and metabolism that can be used to diagnose disease. Despite the abundance of hydrogen, carbon dioxide, and methane that have already been identified in human flatus, the small portion of trace gases making up the VOCs emitted from stool include organic acids, alcohols, esters, heterocyclic compounds, aldehydes, ketones, and alkanes, among others. These are the gases that vary among individuals in sickness and in health, in dietary changes, and in gut microbial activity. Electronic nose devices are analytical and pattern recognition platforms that can utilize mass spectrometry or electrochemical sensors to detect these VOCs in gas samples. When paired with machine-learning and pattern recognition algorithms, this can identify patterns of VOCs, and thus patterns of smell, that can be used to identify disease states. In this review, we provide a clinical background of VOC identification, electronic nose development, and review gastroenterology applications toward diagnosing disease by the volatile headspace analysis of stool. | Daniel K Chan Cadman L Leggett Kenneth K Wang | 2016 | World Journal of Gastroenterology2016，22，4： | 4 |

| 9 | Comparative effectiveness of i-SCAN^(TM) and high-definition white light characterizing small colonic polyps显示文摘AIM:To evaluate accuracy of in vivo diagnosis of adenomatous vs non-adenomatous polyps using i-SCAN digital chromoendoscopy compared with high-definition white light.METHODS:This is a single-center comparative effectiveness pilot study.Polyps(n = 103) from 75 averagerisk adult outpatients undergoing screening or surveillance colonoscopy between December 1,2010 and April 1,2011 were evaluated by two participating endoscopists in an academic outpatient endoscopy center.Polyps were evaluated both with high-definition white light and with i-SCAN to make an in vivo prediction of adenomatous vs non-adenomatous pathology.We determined diagnostic characteristics of i-SCAN and highdefinition white light,including sensitivity,specificity,and accuracy,with regards to identifying adenomatous vs non-adenomatous polyps.Histopathologic diagnosis was the gold standard comparison.RESULTS:One hundred and three small polyps,detected from forty-three patients,were included in the analysis.The average size of the polyps evaluated in the analysis was 3.7 mm(SD 1.3 mm,range 2 mm to 8 mm).Formal histopathology revealed that 54/103(52.4%) were adenomas,26/103(25.2%) were hyperplastic,and 23/103(22.3%) were other diagnoses include 'lymphoid aggregates','non-specific colitis,' and 'no pathologic diagnosis.' Overall,the combined accuracy of endoscopists for predicting adenomas was identical between i-SCAN(71.8%,95%CI:62.1%-80.3%) and high-definition white light(71.8%,95%CI:62.1%-80.3%).However,the accuracy of each endoscopist differed substantially,where endoscopist A demonstrated 63.0% overall accuracy(95%CI:50.9%-74.0%) as compared with endoscopist B demonstrating 93.3% overall accuracy(95%CI:77.9%-99.2%),irrespective of imaging modality.Neither endoscopist demonstrated a significant learning effect with i-SCAN during the study.Though endoscopist A increased accuracy using i-SCAN from 59%(95%CI:42.1%-74.4%) in the first half to 67.6%(95%CI:49.5%-82.6%) in the second half,and endoscopist B decreased accuracy using i-SCAN from 100%(95%CI:80.5%-100.0%) in the first half to 84.6%(95%CI:54.6%-98.1%) in the second half,neither of these differences were statistically significant.CONCLUSION:i-SCAN and high-definition white light had similar efficacy predicting polyp histology.Endoscopist training likely plays a critical role in diagnostic test characteristics and deserves further study. | Johanna L Chan Li Lin Michael Feiler Andrew I Wolf Diana M Cardona Ziad F Gellad | 2012 | World Journal of Gastroenterology2012，18，41： | 3 |

| 11 | Magnetoelectric and converse magnetoelectric responses in Tb_xDy_(1-x)Fe_(2-y) alloy & Pb(Mg_(1/3)Nb_(2/3))_(1-x)Ti_xO_3 crystal laminated composites显示文摘Measured results of magnetoelectric (ME) and converse magnetoelectric (CME) effects of TbxDy1-xFe2-y/ Pb(Mg1/3Nb2/3)(1-x)TixO3/TbxDy1-xFe2-y (TD/PMNT/TD) and PMNT/TD/PMNT laminated composites are pre- sented. ME effect was determined by measuring laminate voltage output under a Helmholtz-gener- ated AC field biased by a DC field (0―1 kOe) (1 Oe = 79.58 A/m). The CME effect was measured by re- cording the voltage induced in a solenoid encompassing the ME sample while exposed to a DC bias field and PMNT layer driven by a 10 V AC source. The ME and CME responses in the two laminated structure are linear. The highest values of ME coefficients in TD/PMNT/TD and PMNT/TD/PMNT com- posites are 384 mV/Oe and 158 mV/Oe, respectively, while the highest values of CME coefficients in the two composites are 118 mG/V and 162 mG/V (1 G=10-4 T), respectively. | JIA YanMin LUO HaoSu OR Siu Wing WANG YaoJin CHAN Helen L W | 2008 | Chinese Science Bulletin2008，53，14： | 3 |
| 12 | Th1 cytokines promote T-cell binding to antigen-presenting cells via enhanced hyaluronan production and accumulation at the immune synapse显示文摘Hyaluronan(HA)production by dendritic cells(DCs)is known to promote antigen presentation and to augment T-cell activation and proliferation.We hypothesized that pericellular HA can function as intercellular‘glue’directly mediating T cell–DC binding.Using primary human cells,we observed HA-dependent binding between T cells and DCs,which was abrogated upon pre-treatment of the DCs with 4-methylumbelliferone(4-MU),an agent which blocks HA synthesis.Furthermore,T cells regulate HA production by DCs via T cell-derived cytokines in a T helper(Th)subset-specific manner,as demonstrated by the observation that cell-culture supernatants from Th1 but not Th2 clones promote HA production.Similar effects were seen upon the addition of exogenous Th1 cytokines,IL-2,interferon c(IFN-c)and tumor necrosis factor a(TNF-a).The critical factors which determined the extent of DC–T cell binding in this system were the nature of the pre-treatment the DCs received and their capacity to synthesize HA,as T-cell clones which were pre-treated with monensin,added to block cytokine secretion,bound equivalently irrespective of their Th subset.These data support the existence of a feedforward loop wherein T-cell cytokines influence DC production of HA,which in turn affects the extent of DC–T cell binding.We also document the presence of focal deposits of HA at the immune synapse between T-cells and APC and on dendritic processes thought to be important in antigen presentation.These data point to a pivotal role for HA in DC–T cell interactions at the IS. | Paul L Bollyky Stephen P Evanko Rebecca P Wu Susan Potter-Perigo S Alice Long Brian Kinsella Helena Reijonen Kelly Guebtner Brandon Teng Christina K Chan Kathy R Braun John A Gebe Gerald T Nepom Thomas N Wight | 2010 | Cellular & Molecular Immunology2010，7，3： | 3 |

| 15 | Development of systemic therapy for hepatocellular carcinoma at 2013:Updates and insights显示文摘A growing number of multi-targeted tyrosine kinase inhibitor(TKI)has undergone testing for hepatocellular carcinoma(HCC).Unfortunately,this enthusiasm has recently been discouraged by a number of negative phaseⅢstudies on several anti-angiogenic TKIs in HCC.Several postulations have been made to account for this phenomenon,namely the plateau effects of anti-angiogenesis approach,the heterogeneity of HCC in terms of background hepatitis/cirrhosis and tumor biology,as well as the way how clinical trials are designed.Regardless of the underlying reasons,these results suggested that alternative strategies are necessary to further develop systemic therapy for HCC.Several new strategies are currently evaluated:for examples,molecular agents with activities against targets other than vascular endothelial growth factor receptor are being evaluated in on-going clinical trials.In addition,different approaches of targeted agents in combination with various treatment modalities,such as concurrently with another molecular agent,cytotoxic chemotherapy or transarterial chemoembolization,are being developed.This review aims to give a summary on the results of recently released clinical trials on TKIs,followed by discussion on some of the potential novel agents and combinational approaches.Future directions for testing innovative systemic agents for HCC will also be discussed. | Stephen L Chan Winnie Yeo | 2014 | World Journal of Gastroenterology2014，20，12： | 2 |

| 19 | TSC1-mTOR-PLK轴以阶段特异性方式调节从施旺细胞增殖到髓鞘形成的内稳态开关显示文摘恰如其分的外周髓鞘形成取决于雪旺细胞增殖与分化进程间的平衡。丝氨酸/苏氨酸激酶(mTOR)整合多种环境因素,是细胞生长、代谢、发挥作用的中枢调节者。本文报道了一种mTOR的负性调节剂——结节性硬化复合体(TSC1),通过控制细胞增殖和髓鞘稳态,建立了雪旺细胞谱系进展和髓鞘形成的阶段依赖性程序。小鼠雪旺细胞祖细胞中TSC1的解离导致mTOR信号通路激活,继而导致雪旺细胞过量增殖,分化受阻,髓鞘形成减少。转录组分析显示,TSC1突变体中的mTOR活化使得polo样激酶(PLK)依赖性通路和细胞周期调节剂上调。弱化mTOR或者对PLK进行药理抑制部分挽救了因TSC1缺失导致的外周神经发育过程中的髓鞘形成减少。相较之下,成年小鼠成熟雪旺细胞中TSC1缺失可导致髓鞘的过度增殖和过度生长。本文的发现提示了TSC1-mTOR-PLK信号轴在控制雪旺细胞的发育过程中,从增殖到分化和髓鞘内稳态中起到的阶段特异性功能。 | Jiang M Rao R Wang J Wang J1 Xu L Wu LM Chan JR Wang H Lu QR 聂昊(编译) | 2018 | 神经损伤与功能重建2018，13，5： | 2 |
